I'm new to the Facebook developing side of things and have recently added two applications to Facebook and linked them to my Fan Page. The Fan Page and two Applications are not yet live, therefore, I cannot provide any live demonstrations.

One of these applications is an on-line based Radio and I am trying to set up an API Graph so when they click to 'Tune In' it'll post to their wall with the following information:

Radio Name
Current show
Current presenter(s)
Current listeners
Image

I have created an action, however, I do not know exactly what my action does and how to use it and could really do with some help.
